f5 and frictional floor engaging member.

An object of the invention is to provide a simpliiied structure,inexpensive to manufacture, and capable of production in large numberswith relatively little labor costs.

Another object of my invention is to so construct the cushion footassembly per se that the yieldable cushioning material is rmly tied intoits positioning element to provide arigid, integral assembly.

A further object of my invention is to so couple the cushion footassembly with the chair leg that it is readily removable therefrom forreplacement purposes, and at the same time securely positioned on theleg during its useful life.

Various other objects and meritorious features of the invention will beapparent from the following description taken in conjunction with thedrawing wherein like nu- 25 merals refer to like parts throughout thewill be apparent that other types of yieldable material may be utilizedin lieu of rubber.

Fig. 1 illustrates a conventional type of folding chair embodying frontand rear legs and l2 respectively, upon each of which is shown a cushionfoot assembly illustrated broadly by the numeral 14. A metal stamping 16is utilized for securing the assembly to the legs 10 and 12 of thechair, one end of the stamping being formed to interlock 1931. SerialNo. 537,632.

firmly with the cushioning material. In the preferred from illustratedin Figs. 24 thisv stamping comprises a flat strip of metal which isfolded over at one end to form a triangular unit 18, the three sides ofwhich are apertured as illustrated at 20.

A cap member 22 includes depending side flanges 24 exending around theperiphery thereof and a slot 26 for the purpose of receiving thestamping' 16. The folded eX- 60 tremity of the stamping is bent over thetop of the cap as indicated at 28 after the cap has been positioned andthe rubber foot 30 is molded in `situ about the supporting assembly, theapertures 2O permitting this opera- 65 tion. In this way the rubber istied into the stamping, at the same time surrounding it, and forming anintegral structure of great durability.

In the structure illustrated in Figs. I have shown one type of chair legwith which my improved cushion foot is adapted for use. rlfhis leg 32consists of strip. metal which is rolled overalong either one or both ofits longitudinal edges as at 34 and 36. In positioning the cushion footupon such a leg, the positioning arm of stamping 16 may be insertedunder the rolls as clearly illustrated in Fig. 4 to be positionedthereby, or the said positioning arm may be placed in juxtaposition tothe flat portion of the leg 32 and the longitudinal edges thereofsubsequently rolled over to position the cushion foot assembly.

To further insure the permanent position- 2 and 4 7 ing of the footassembly I have illustrated a socket 38 in the positioning arm ofstamping 16 which is adapted to engage a protuberance 4() provided inthe flat portion of the leg 32. This constitutes what may be regarded asa snap fastener. served that in this preferred structure I have utilizedbut a single positioning arm. However, the side thrust upon the cushionfoot assembly is adequately resisted in both It will be oblateraldirections by virtue of the turned over end portion 28 of the stamping,thereby insuring rigidity of the assembly and the leg.

In Fig. 6 I have illustrated a somewhat different assembly wherein thestamping includes a plurality of positioning arms 42 eas and 44 whichare riveted as at 46 to the flat portion of the leg 32. Obviously theleg may be of the type illustrated in Fig. 2 or any other type wherethis structure is utilized.

In Fig. 7 a different type of chair leg 48 is illustrated and the twopositioning arms 50 and 52 of the stamping .extend through spaced apartslots in the cap 54, thereby permitting the arms to lie against eachside of the leg 48 and secured thereto by suitable means such as rivet56.

Various other modifications of the structure herein illustrated will beapparent to those skilled in the art and for that reason I wish to limitmyself only within the scope of the appended claims.

I claim:

1. A cushion foot assembly comprising a flanged cap having an aperturedtop, a shank element associated with said cap, said shank element bentupon itself providing arms extending upwardly through the apertured topof the cap and a hollow tubular extremity at the bend disposed withinsaid cap, and yieldable cushioning material molded in situ about andwithin the tubular extremity of said shank within the cap.

2. A cushion foot assembly comprising a cap having depending flangesabout its periphery and an apertured top, a shank element associatedwith the cap, said shank element comprising a fiat metal strip bent uponitself providing arms extending upwardly through the apertured top ofthe cap and a hollow tubular bend forming the extremity within the cap,said cap seated upon said tubular bend extremity and cushioning materialmolded in situ about and within said tubular extremity within said cap.

3. In combination with a chair leg having longitudinally rolled edges, afoot structure therefor comprising a flanged cap having an aperturedtop, a shank element having a hollow head portion disposed within saidcap and a block of cushioning material disposed within the cap about andwithin said head, said shank element having an end portion extendingthrough the apertured cap and upwardly along the leg underneath therolled ovei` edge portions.

4. In combination with a channel form chair leg, a foot structuretherefor having a shank element secured to the leg within said channelheld against displacement by the channel walls, said shank elementrolled upon itself at its lower end forming a tubular portion extendingtransversely the chair leg below the end thereof, and cushioningmaterial molded within and around said tubular portion.

5. In combination with a chair leg, a foot structure therefor comprisinga shank element bent upon itself to provide a hollow tubular portionarranged at the end of the chair leg with an end portion of the shankelement overlapping and secured to the chair leg and cushioning materialmolded within and about said tubular portion of the shank element.

6. In combination with a chair leg, a cushion foot structure associatedtherewith comprisinga shank element formed by a flat stamping foldedtransversely upon itself adjacent one extremity to form a tubular head,a slotted cap receiving said stamping and seated upon said head, thefolded extremity of said stamping being doubled back through the slot inthe cap and turned over the upper face thereof, and cushioning materialmolded about said head within said cap.

7. In combination with a chair leg, a cushion foot structure associatedtherewith comprising a shank elementformed by a flat stamping foldedtransversely upon itself adjacent one extremity to form a tubular headhaving apertures in its side walls, and a slotted cap receiving saidstamping and seated upon said head, the folded extremity of saidstamping being doubled back through the slot in the cap and turned overthe upper face thereof, and yieldable cushioning 1naterial positionedwithin the cap about and Within the tubular head.

8. In combination with a chair leg having longitudinal tubular edgeportions, a cushion foot structure therefor comprising a flanged caphaving an apertured top, a shank element associated with said cap andcomprising a hollow head portion disposed within the cap and a singleportion extending upwardly therethrough and into each of the tubularedge portions of the leg of the chair to be frictionally engagedthereby, and cushioning material disposed within said cap completelysurrounding the walls of the head on the shank element.

In testimony whereof, I, GEORGE D. Somm- MERHORN, sign thisspecification.
